Specification of Letters Patent.

Application filed February 11, 1911.

Patented J rule 2, 1914; Serial No. 607,898. a

To all whom it may concern:

Be it known that 1, CHARLES L. HOLDEN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Water-Heating Appliance, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to an improvement in pipes through which heat may be conducted, the invention having reference more particularly to draft pipes for furnaces, ranges or stoves which serve the purpose of carrying away smoke or the gases of combustion as well as producing draft for the fires.

The object of the invention is to provide an improved draft pipe of the above-mentioned character that will be adapted for utilizing the heat of the draft currents for heating water for domestic or other purposes, more especially for kitchen or laundry use; a further object being to provide an improved water heating appliance that will not be liable to become coated internally with scale or sediment due to water containing lime or other matter which may be separated therefrom under a high degree of heat, a still further object being to provide an improved waterheating appliance that will be adapted especially to be used in kitchens at relatively small cost in lieu of expensiveand troublesome water backs commonly used in the fire-boxes of ran es and stoves, all to the end that economy s all result in operation, and that the disadvantages of extremely. hot water may be avoided.

WVith theabove-mentioned and minor objects in view, the invention consists in an lmproved draft pipe section provided in ,one portion thereof witha heating boiler or 0011 through which the water may circulate in the process of heating it by the current of heat passing to a chimney, the section being provided with a by-passage extending past the heating boiler, and a valve or gate for regulating or changing the draft current with respect to the by-passage and the portion of the section having'the water heater therein; the'invention consisting further in the parts, and combinations and arrangements of parts, as hereinafter particularly described and claimed. 7

tation of the invention for domestic Referring to the drawings, Figure 1 is an elevation of a kitchen range having the improved draft pipe connected therewith and a tank or reservoir connected with the heating-boiler; Fig. 2, a vertical or longitudinal central sectional view of the improved water heating appliance; Fig. 3, a fragmentary perspective view of the valve or gate and supporting and controlling devices thereof; Fig. 4, a horizontal section on the plane of the line A A in Fig. 2 with the regulating valve adjusted to a different position so as 130%)61111111 the water to be heated; and Fig. 5, a ragmentary section illustrating the controlling devices of the valve or gate.

Similar reference characters in the different figures of the drawings indicate corresponding elements or features of construction herein referred to.

In the drawings, as illustrating the adapurposes, a kitchen range 1 is illustrated w iich has a fire-door 2, an oven-door 3 and a top 4, a reservoir or tank 5 being arranged in proximity to the range or stove and having a cold-water inlet pipe 6 connected there with, a circulating pipe 7 being connected with the bottom ofv the reservoir through which to conduct the cold water to be heated, a circulating pipe 8 being connected to he upper portion of the reservoir for conducting the heated water to the reservoir, the latter having a pipe 9 connected with its upper end through which the hot water may be drawn from the reservoir.

As preferably constructed the invention includes a chambered draft pipe section comfprising a tubular body portion 10 which pro erably is oblong and may be substantially oval in cross-section, a tapering end portion 11 being attached to the body portion and having a nipple 12 on its smaller or lower end adapted to be connected to a range or stove, as shown, or with a section of stove-pipe. The body portion 10 has a longitudinal partition 13 therein which extends across its interior in the plane of its smaller dimension so as to divide the interior into two channels or draft passages. The opposite or upper end of the body' portion 10 has'a tapering portion 1 1 thereon and its smaller end is adapted to be inserted into one end of a stove-pipe 15 which preferably is provided with a well known type of damper 16 having an operating handle 17 for regulating the chimney draft. The body portion 10 has a doorway 18 in its wall and is provided with a hinge-pin 19 at one side of the doorway and at the opposite side of the doorway with a catch 20. A door 21 is connected at one side to the. hingepin so as to normally close the doorway, and is provided at its opposite side with a latch adapted to engage the catch 20.

A suitable circulating conduit or heating boiler is provided and arranged in the draftpipe section at one side of the partition and adjacent to the door, so as to be accessible in order to brush soot therefrom. The heat.- ing boiler preferably is similar to the type described and claimed in my pending application for Letters Patent of the United States, Serial No. 561,369, filed May 14, 1910, and comprises a suitable number of chambered sections 23, 23, 23", adapted to expose the circulating water most advantageously to the effects of the heat currents,

- the sections having very large heating surfaces and are connected together in stagge-red arrangement by means of nipples 24, 24, the lower end of the lower section of the heating boiler having a pipe 25 connected thereto which extends downward and thence outward through the wall of the body portion 10 and is connected to the cold water pipe 7 by means of a union 26. The upper end of the uppermost section of the heating boiler has a circulating-pipe 27 connected thereto and extending upward and thence outward through the wall of the body portion 10 and is connected to the hot-water pipe 8 by means of a union 26, the wall of the body portion 10 serving to hold the heating boiler in the desired position in the draft passage at one side of the partition. the space at the opposite side of the partition serving as a by-passage when it is not desired to heat the water or to increase the temperature of the water. A. shaft 28 is rotatively mounted in the draft pipe section adjacent to the lower end and in the same plane with the partition 13 and preferably has a lug 29 on its body portion, the shaft being journaled in suitable openings 30 in the wall of the draft pipe and has a squared shank 31 for its control. A corrugated or serrated plate through which the shaft extends is secured to the exterior of the draft-pipe section by means of the ears 32, and a corresponding corrugated plate 33 has a squared hub 3 :3 arranged slidingly 011 the shank 31 so as to coiiperate with the plate 32 to prevent rotation of the shaft except when purposely rotated. A valve or gate 34: is provided which approximately closes one passageway at either side of the partition 13 when properly adjusted, and it has eyes 35 receiving the shaft, one eye having a recess 36 therein to receive the lug 29 whereby the valve may be turned as on a hinge by means of the shaft. A handle 37 is provided which has a hub 37' that is secured to the shank 31 for operating the valve, and a coil-spring 33 is placed on the shank 31 against the hub 37 and the plate 33, the spring normally holdin the plate 33 in contact with the plate 32 and also holding the lug 2i) in the recess 36 with the valve against the inner side of the wall of the draft pipe section. The arrangement is such that when the gate 3% is horizontal'so as to close the byassage at one side of the partition as shown in Fig. 4:, the handle 37 is horizontal. Suitable words are placed on the face of the handle, such as the word On as at 39, to indicate that the draftcurrent is on the heating boiler, and another word as Off, as at 40, is readable on the handle when inverted with the gate extending across the passageway leading to the heating boiler, to indicate that the heatcurrent is deflected therefrom and into the by-passage.

In practical use, if the reservoir 5 is supplied with cold water and a fire maintained in the range or stove the smoke if any, and draft current heated by the fire, as will be understood passes to the chimney, but in the present case much of theheat is abstracted by the circulating water, when the bypassage is closed by the valve or gate 3 so that the draft current is compelled to pass in contact with the heating boiler or conduit on its way to the chimney. In case the water becomes sufficiently heated and little or no water is being used from the reservoir, the valve 01' gate may be adjusted to any desired position as indicated by detted lines in Fig. 2, so that the draft current may pass at both sides of the partition in any desired ratio to maintain the water at the desired temperature, or the valve may be adjusted as in Fig. i, so as to shut off the current from the heating boiler entirely, thus fully opening the by-passage. It will be understood that when there is no smoke passing off from the fire the damper 16 may be partially or wholly closed, if desired, to prevent the escape of heat and utilize it for heating the water to a higher temperature.

Having thus described the invention, what is claimed as new, is

1. In a water-heating appliance, the combination of a draft-pipe section body portion that is oval in cross section, a partition attached at two opposite edges to two opposite portious respectively of the wall of the body portion, the partition extending across the body portion on the minor axis thereof and from one end to the opposite end of the body portion, two tapering end portions attached at their larger ends to the two opposite ends respectively of the body portion, a pipe extending through the wall of said body portion adjacent to the larger end of one of said end portions, a pipe extending through the Wall of said body portion adjacent to the larger end of the remaining one of said end portions, and the heating boiler in said body portion at one side of said partition, one end of said boiler being connected to one of said pipes and the opposite end connected to the remaining one of said pipes.

2. In a Water-heating appliance, the combination of a draft-pipe section comprising a body portion that is oval in cross'section and two tapering end ortions secured to opposite ends of the boy portion, a partition in the body portion extending in the plane of the lesser transverse dimension thereof and secured to opposite portions of the Wall of the body portlon, a shaft rotasections being opposite one of said tapering portions, another one of the boiler sections being 7 pposite the remaining one of said tapering portions.

In testimony whereof, I afiix my signature in presence of two Witnesses.
